Green Energy Videos
Informative, how to, green
energy videos may be placed on this page with a description and a link. All I need is your youtube small frame embed code, a link and a
description. Your how to video should help us become more energy independent. Renewable green energy
such as solar, wind and geothermal is the way of the future and I am hoping that
together we can spread the word and help create a better world for ourselves and our
This is an experiment designed to demonstrate the relationship
between collecting solar heat and storing solar heat. Notice that both
bottles of water get hotter when the sun strikes them. The painted
bottle gets hot faster but the felt covered bottle retains heat longer.
Modified Trickle Down solar heating was designed to lower
the cost solar heating application for do-it-yourselfers. Modular
collectors use inexpensive black polyester felt rather than expensive
absorber plates and expensive flow tubes.
The downspout collector is a simple unobtrusive way of
collecting solar heat as long as you have the sufficient sunlight on the
south side of your house.
This 8' x 24' collector was built in place and mounted on
poles on the ground. The absorber plates were made from aluminum fins
and and the flow tube was made from 3/4" PEX. Scott will explain it
How can we place a value on sunlight? In 2011 we say oil
has a retail value of $4/gallon and electric power has a value of
.$0.20/ KWH but how can we place a dollar value on sunlight? Can
homemade solar applications save heat and actually provide a source of
Our Big Sun provides us with a direct connection to the
energy from the universe. The dawn of a solar age has is here now and
there will soon be many local green energy opportunities for everyone.
Start small but think big like the sun.
The oblique rays of a
January sun offer little warmth but if your collectors have a steep
pitch and your not surrounded with trees it's possible to to solar heat
your house in the dead of winter with a sunshed.
The efficiency of heat
transfer can be improved by using multiple tanks designed to increase
heat stratification. This method is used to trap hot water and return
cold water to the collector.
The Solar Workshop has
been designed to maximize both the work space and the surface area for
heat collection and storage with a minimum of low cost materials. Heat
storage drums are installed inside an insulated shed on the North side
of the shop to conserve work space so that the south side of the shop is
free to receive a winter's sun.
Direct connect solar
hot water systems are connected directly with a homes hot water plumbing
system so that heat transfer coils are not necessary. Direct connect
systems are used in areas where freezing is not a problem. Drain down,
direct connect systems have been used in cold climates, but if the
emergency drain down fails freezing water could damage pipes.
The one LED
differential controller uses thermistors to sense the differential
temperature between collector and storage tank. It's a rugged little
controller capable of regulating a 300 watt pump, but it only has one
LED that comes on when the pump is activated.
The two LED
differential controller is almost identical to the one to the left but
it has an additional LED used to monitor heat availability. The red LED
glows in proportion to the heat energy available and the green LED turns
on when the pump is activated.
